Continuous current micro-ohmmeter with increased output capabilities and continuous current (200 A DC) generation during the static resistance measurement.
Portable micro-ohmmeter with Both Sides Grounded and Remote Control features generating up to 800 A.
Contact resistance measurement is one of the most important and common tests during switchgear manufacturing, commissioning and maintenance stages. Besides switchgear testing, the RMO digital micro-ohmmeters are designed for simple, safe and efficient testing of:
All DV Power RMO micro-ohmmeters use Kelvin’s 4-point measurement principle which is the most convenient for very small resistance measurements. The measurements are accurate and in accordance with international standards for AC high-voltage circuit breakers testing (IEEE C37.09 and IEC 62271-100).
Starting from 2003, DV Power has been a trendsetter on the market when our first 500 A micro-ohmmeter weighing only 8 kg (RMO500A / CPM500) was released.
Currently, DV Power micro ohmmeters portfolio includes 19 models, divided into 4 series:
The instruments generate a user-selectable and ripple-free test current up to 800 A in an automatically regulated test ramp. Test current ramping significantly decreases the influence of the magnetic transients to measurement.
